Be itknown that we,l FRANK M. PETERS and WARREN-H. HNGERIORD, v-)th citizens of the United States, residing at Chicago,

'in the county of Cook and State oflllinois,"

have invented certain new.` and useful lm provernents in Flat-Icing Machines, of which the following isaspeci cation. `v Our invention has reference morefpar-k 'o'vticularly to amachine. for 'applying a coatingof` frosting, icing yor lling'y to the surface ofllca'kes, cookiesand the yike, wherein the cakes or cookiesy are ,constantly fed from a magazineorother' suitable scurce of sup'- l 1.5, ply and thefcoatin' automatically-applied to prnvidean improved'niaehine which will '20 `mit oinaticall'y apply pa coating of icing or similar, 'xniateriadVIA to' cakesQor cookies; to' rovide'such ai'machine with ad-y mechanism for automatically feeding the- .ca'kes or cookies Eto the Dc ating mechanism from a supplyin a magmuine;v to' interpose-a v filling betweensuperposed cakes or cookies;

One of Ithese Aconnectors is llocated at the front of to support the forward, cadente plurality of wood stri s: 3 and 4, wh1ch extend-"from apart, from one anothei'toaord lorgltudis i along strips `3 and 4 and supporting said strips on..

ject and operate for sliding the cakes along the Supporting surface of the machine. Near the rear end of the machine and also at an intermediate point, are frame cross connectors 6 and 7, each of which is set down below the top of they machine and has short posts or pedestals 8 corresponding to the the upper ends thereof, the purpose of this construction being to afford openings beneath each slot in which the rods of the l frame which carries the lingers for moving the cakes are located and operate.

This machine is designed to have a lseries of .cakes ymovin through the machine simultaneously and may be made ofthe width desired to accommodate the number of cakes to be moved through the machine at the same time. The cakes move. directly along and over the` strips 4 and extend over the slots 5 1at each side of, the strip ontothe adjoining strips 3, andthe strips 4, because of theirna-rw row .width and the break in the length .thereof,which will `be hereinafter morefparticularly explained, lare preferably mounted in channel lirons 9.

At the forward end ofthe machine over each ofthe strips 4 is amagazine 10,'the number of maga-zines depending upon the particular capacityof the machine,` and these magazines are held with `their lower ends elevated above the surface of. the strips 3 and 4, adistance somewhat reater than the thickness of one of the ca es, so that the latter may be withdrawn one at a time from the lower end of each magazine'. VFor supporting the magazines, a plate 11 is secured toand extends'up above each side frame 1',

andfeach Vhas front and rear angle brackets 1,2, upon the upper anges of which are secured crossbars`13 and 14 extending across the machine and arranged in spaced relation to accommodate the magazines therebetween. These magazines each comprise a pair of `oppositel arranged upwardly extending trough s aped members 15, which` may be of angular form as shownin Figure 16, and

Y are arranged inopposed relation so as to serve as a substantial enclosure for a stack of cakes therein. One of the members 15 of each magazine is mounted by means of a bracket 16 0n the cross.bar 14, andthe other member 15k by asimilar bracket 17 on the cross bar V13, and the ends of the bars 13 and 14 have corresponding diagonal slots 1,8 and 19 whereby thebars are adjustably secured to the, brackets 12, so that the distance between the bars may be regulated to enlarge .or diminish the size ofthe magazines and at thesame time maintain the proper relative position of the members `1,5 to embrace cakes of different sizes therebetween and discharge sainer in theproper position onto the strips therebelow. y v a For advancing the cakes, which we have rodsv21 by the intermediate rods 23, one of which is located directly belowy each slot or passageway 5 of the machine top. Each rod 23 has correspondin pins 24, 25 and 26pmjecting upwardly tlgierefrom rand operating through the slots 5'so as to move thecakes along the machine top. a

[The frame comprising the rods 21 and 23 and cros'sibars 22 and27 constitutes the main cake, advancingframe,which, however, is supplemented by a plurality of bars28 which 'extend beyond'thebar 27 in vertical alignmentvith theA rods 23. These bars 28 arearran'g'e-d inpairs, each pair of which embrace o neV of 'the ynarrow vstrips 4 of the machine top fand each pair is mounted on -a bracket 29,.which latter is secured to the bar 27 and holds the bars 28 at a somewhat higher elevation than the rods 23, and each bar 28 is provided with cake engaging pins 30, which because of the higherelevation of the bar 28 are shorter than the pins 24, 25 and 26. Shafts 31 and 32 extend' transversely of the machine adjacent the' ends thereof, and are journaled in suitable bearings provided therefor in ther side framesl. Above the end of each shaft 31 andl 32, `im-y mediately inside the respective frame A1, is a short u right shaft 33 which is'mounted ina brac ety 34,' whichv latter is secured to the respective side frame 1 and provided with a vertical bearing in ywhich' the vshaft shaft 31, or'32, as the case may be. 'Cams 37 are secured onv the shafts 311-and 32 adjacent each yoke 36 and provided withy an 33v slides. Each of the shafts 33has a halfl bearing 35 on the upper end in'fwhichv the side rod 21 of the main cake movingframe is supported, and atthe lower 'end ofeac-h shaft 33k is a-yoke 36 which 4straddlesthel elevating portion 38 along about one-fourth ofthe periphery,.and each of the yokes 36 has a roller 39 resting on the periphery of the cam 37 and adapted whenk the elevating portion of the cam engages therewith to ele'- vate theshafts 33 and their halfbearings 35 which support the main rframe 22,23, 27,

and elevate the latter so that the pins 24,

'25, 26 and 30 are projected ashort distance abovethe v upper surfacel of the strips and 4 which constitute the top 'of the machine.r When the rollersV 39 arenot engaged with the elevating portion 38 of the'cams, the cake advancing-frame is depressed by gravity,

and at such times the cake advancing-pins are maintained below the upper surface of the strips V3 and 4.

The shafts 31v and 32 operate simultaneously and at a corresponding rate of speed, and the cams 37 are arranged on the s afts 31 and 32 so that all the rollers 39 are engaged at the same time by the elevating portions 38 of the cams so as to effect a uniform elevation and depression of all parts of the cake-moving frame.

A side rail 40 is mounted at each side of the machine on the upper edge of each of the frames 1, said rails being correspondingly constructed and positioned, and extending between the first magazines 10 and the second magazinesv 41, and intermediate of their ends, each ofthe rails 40 has an' elevated portion 42 which serves to support a hopper 43 at a slight elevation above the upper surface of the strips 3 and 4 of the taple-top. This hopper extendsfrom side to side of the machine and rests upon the top ofacross-plate 44, the ends of which extend over the elevated portions 42 of the side bars 40 and are bolted directly thereto. The plate 44 is of suicient thickness so as to prevent sagging thereof intermediate of the ends, and has hinge lugs 45 at one end, as shown in Figure 15, and the hopper 43 has corresponding hinge lugs 46 at one end through which a pivot bolt 47 is engaged, so that the hopper may be swung up off of the cross-plate 44, when desired, for greater convenience in cleaning and washing out the hopper without the water used for washing running down onto the machine. This hopper 43 may be of any convenient form and is provided with a slot 47 in the bottom extending across the machine and controlled by a valve 48 carried by a shaft 49 which projects through the end walls of the' hopper and has a handle 50 thereon outside one of the end walls of the hopper, whereby the valve 48 may be operated. The crossplate 44 also has a slot indicated at 51, which corresponds to and registers with the slot 47 in the bottom of the hopper, said slot being preferably tapered by having one. edge thereof beveled, as indicated in Figure 5, to afford an outlet at the bottom of narrower width than the entrance into the slot at the top.

It is necessary to clamp the bottom of the hopper 43 tight against the upper surface of the cross-plate 44, so as to avoid leakage of the material in the hopper, which material is usually of a semi-fluid consistency, and for this purpose a number of eye-bolts 52 are pivoted at intervals along the edges of the cross-plate 44 and adapted to swing between correspondingly spaced pairs of lu along the lower edges of the hopper 43, so that the bolts may be readily engaged or disengaged therefrom and utilized to clamp the hopper downV tight against the cross- Iplate 24.

rails'40, so that the upper surface of the plate 54 is flush with the upper surface of the side rails 40. This bottom plate has a lip 55 extending alon the forward edge to afford a support for t e rear edge of'a stencil plate 56, which likewise extends vfrom side to side of the machine. The forward edge of the stencil plate 56 is supported on a corresponding lip 57 of an adjustable cross-bar 58, the ends of which extend over andengage in recesses 59 of the side rails 40, so that the upper surface of the adjustable bar 58 is in the same horizontal plane as the upper surface of the bottom plate 54. The stencil plate 56 is of thin material and the lips 55 and 57 which support this stencil plate are arranged at a proper distance below the upper surface of the plates 54 and 58, so that the Astencil plate 56, when restin on the lips 55 and 57, is iush with an forms a continuation of the upper surface of the plates 54 and 58. The cross-plate 58 isslidable in the direction of its width to and from the front of the machine, so as to serve as a clamp for engaging and holding the stencil plate 56 in position, the purpose of such adjustment being to permit removal of the stencil plate and enable other stencil plates to be employed for frosting cakes and cookies of various sizes and shapes, thus 'iving the machine a wide range of uti 1t For adjusting the clamp plate 58 there 1s a shaft 60 extending across the machine and journaled in the forward ends of the side rails 40. This shaft has a short crank-arm 61 at each end, each of which is connected- 61 are thrown down to the position shown in Figure 1, in which they engage a stop pin 63, each crank-arm 61 and its link 62 are in alignment, or slightly beyond the position of alignment, and 'the cross-plate 58 is projected to the extremity of its movementand thereby locks the stencil plate 56 in place. Either one or both of the cranks 61 may be formed with a handle 64 for operating the shaft 60 to adjust the clamp plate l58. The clamp plate 58 is held down in the depressions 59 by an overlying bar 65 at each side of the machine, the ends of which are bolted to the side rail 40 in any convenient manner.

The stencil plate 56 has a plurality of openinos 66 therein, the number thereof corresponding to the number of rows of cakes which are adapted to be carried through the machine, and each openingl in the stencil vplate overlies the line of travel of a row *of cakes. The stencil openings 66 are made vof suitable length (that is, the thereof transversely oftthe machine) so that will Straddle or"".. extend across the wi est openings Gti-.which may be employed.`

to conform` to the size and shape of the par ticular cakes which are to be coated, and it is for' this reason that the stencil plate .is made removable; that is, so that plates with diiferent sizes or shapes of openings, as may be required, may be employed for frosting or coating vthe cakes of various sizes and shapes in the same machine. Also the thickness of the stencil plate determines the thickness of the coating to be .applied tothe cake,

land the thicknesspmay also be varied if desired.

For applying a :frosting or coating to the cake through the stencil openings 66, the

plunger or slide -53 is arranged to recipro-V cate longitudinallyon the machine at proper intervals, so as to carry charges of frostin or other coating material from the magaz1ne43 to the stencil openings 66; vand th1s slide or plunger has a plurality of openings 67 therethrough adjacent the forward edge and corresponding in number to the number of stencil openings 66 and adapted, when the plunger is in the rearmost position, to register with the outlet from the slot 5]; ofv

the cross-plate 4.4."yThese openin s 67 are the in the stencil plate, and are of suitable depth and width to .contain sufficient coating material to insurenthor'ough coating of a'cake of the largest size, andthe. length of stroke of the plunger or slide k53 is suli-.

cient to carry the openings 67 clear beyond?A the largest opening in the. stencil plate, as indicated by the dotted lines in Figure 5. The bottom plate 54, clampplate 5.8 and stencil 56 form a uniform-l. surface` over..

which the Vplunger or slide5 3 operates, Whichsurface isush with they upper edges of the side bars 40 along which the ends of the :plunger 53 slide, and these plates formf l. j a bottom closure for the openings 67 so that thelatter afford pockets to receive malterial from the magazine 43 and transfer same plate.

.to vthe openings through the stencil Assuming that a cake is held up against the stencil plate 56 directly under one of the openings 66 therein, it will be observed that as the. plunger 53 moves forwardly, the

chargeof material in the openin 67 1s peimitted to lflow and spread over t e ex sed -f upper surface of the cake, such deposit bevving facilitated by the beveled 'edges 68 at .'each side ofthe opening 67, which in both the -forward and reverse movement of the slide 53 serve toforce the contentsof the opening 67 down'onto the surface. of the imension.,`

cake which .is exposed through the stencil openin prefera ly of the Asame form asv the loutline yof the cake and of slightly smaller dimensions, so that the edges of the cake, when elevated, engage against 'the edges of the.

opening and result in a deposit of coating y which does not completely cover the upper surface of the cake. This isnot only a matter of convenience in the operation of the` machine and insures complete closing of the stencil opening so as to avoid leakage of the coating material around the edges of the nected through links 70 with the ends of a cross-bar 71 which extends across the machine at the rear edge of the plunger 53 and is embraced by boxings 72 thereof, which are suitablg aperturedto receive the bar 71 therein. et. screws 73, threaded through thevvallsA ofrboxings 72 serve yto lclampthe' cross-bars 71 securel Heating-"the links. 70 to the cross-bar 71, 4the latter is preferably provided with a. pivot in place. -For cons bracketx74at each end, the vertical dimen-.'v 'i sion of lwhich is substantially the same as the thickness of the plunger or slide 53; and',

these brackets slide upon the upper surface ofthe side rails 40l and are held down thereu agalnst by straps 75, which at their rear, 105.

endsv are secured to an upward extension 76 at the rear of the side rail, and at' the forward ends have a vertical lian e 77 which is, bolted tor the rear edge o' the crossplate 44,

The levers 69 are swung on their pivots lto effect the reciprocation of the plunger vvor slide 53 by links 7 8, .the rear endsof which are pivotedto the lever 69 intermediate of the ends of the latter and .the forward ends of which are divided so as to straddle a shaft 79 -which extends from side'to side of the machine and is journaled in the-side frames 1, and provided at each end with a cam disc 80, havingl a groove 81 and an in-z ner face which engages a roller 82 on the .link 78, whereby a properly timed reciproeating-movementA is imparted to the latter.

The cross-platesv 54 and 58 and the stencil 56`are elevated above the upper surface of the strips 3 and 4 to afford ample space for cakes of any desired thickness to be moved thereunder along the strips 3 and 4,1which movement is effected ina step by! stepfman- 11er by the fingers on the `frame 22, 23, 27,

which is so arran ed that at the'intervalof rest in the step y step movement-of the cakes, a. "series of cakes is brought to rest directly under the stencil openings 66, and when so positioned it vifs-'necessary to elevate the series of cakes to engage the stencil L' plate and close the openings 66 therethrough.;

For this purpose there is a lifter mounted `concentric with and directly below eachV openin 66 and comprising a substantially triangu ar head 83, the upper surface of which is normally Hush with the upper surface of the'strips 3 and 4'and has a depending stem 84 which is journaled in upper and-l lower bearin 85 and 86, respectively, ofa cross-plate 8 which extends from side to side of the machine at a distance below the strips 3 and 4 and has lthe ends secured to the side frames 1. Each stem 84 inte-rma.v

`diate of the bearings-85 and 86 has a-collar 88. x'ed -thereon and formed with a flange or shoulder 89 havi a straight'edgev at one side which slides along a pair'of ribs 90on the cross-plate 87, which are suitably spaced to hold thecollar 88 f and the steml 84 connected therewith, and consequently the head 83 at the upper end ofthe stem, from turning in the bearings 85 and 86. A coil spring 91 is interposed between the collar 88 and the lower bearing 86 so as to have a constant tendency to elevate the stem,84 and the supporting-headV 83. The lower bearing 86 preferablycomprises a sleeve 92 which has a threaded engagement with the depending arm 93 of the cross-plate'87 and is formed with an annular flange 94 at the upper end, against which the lowerl end of the spring 91 is seated. -The purpose of this construction is to `afford an adjustment whereby the tension of the sprin 91 may beregulated. j

For controlling t e elevation of the stems 84 and supporting heads '83, which ythe springs 91 tend tocause, there is a shaft 95 extending from side to side of the machine and journaled in the side frames 1 at a dis-- 'tance rearwardly from and parallel with the series of stems 8 4, andA thisshaft has a series of rocker arms 96`fixed thereon, corresponding in number to the stems 84, and each one of these rocker arms extends forwardlyv and has theforward end divided so as to straddle the correspondingstem 84of the cake lifters and bear against the upper face of they .collar 88 on the stem. A shaft 97 extends from. side to side of the machine Iabove the series of rocker arms 96, substantially midway between the front and rear ends thereof and is ournaled in the side frames 1. This shaft as a cam 98 at each end adapted to engage a roller 99 on the corresponding end rocker arm 96, which cam, throughoutthe larger part of its periphery, is of' proper `'diameter to permit the stems and supporting-heads 83 to Lpbelifted by the tension' of the springs l91 to the-proper elevation tohold a cake resting on the headv 83 against' the undersurf'ace of the stencil plate 56. The/se cams 98 each have an enlargement 100"which at the;l proper times-'that is, at the time w en lthecakesare advanced' alon'l the surface of the machine engage'therol ers 99, thereby rock 'the shaft 95 and thereby vdepressthe intermediate rocker arms96 sothat alll ofthe stems 84 are depressed and the cake-support-` ing heads 83 depressed to a position where- ,ein the upper surfaces thereof are flush with the upper surface of thestrips 31 and y4, thus depressing'the outer rockera'rms 96 so as to another 'cake to be moved onto the head' for elevation' to the `coating position.v Obviously, iff'cakes of different thickness are frosted in this machine, the elevation of the heads83; must be regulated in accordance with the thickness of the cake, and for this' purpose'the collars 88v are secured on `the stems 84 byI set screws 101,which`enable the collars to be positioned onthestem so' as to afford the r and leave tiie tween the upper surface ofthe head and the lower surface of the stencil platel56. y It is desirable that' the `head 83 shall'be oper elevation of the headsk83 required space' for the cake beof suitable dimensions to reach out close to' v e vthe edg'eof the cake supported thereupon,l lso as to ai'ord a substantial support for the cake, and the headis,l therefore, necessarily 'wider' than the strip 4.alongk which the cake is advanced through-the machine, and itis,

moreover, necessary to arrange the cake# advancing pins on the frame l22, 23,vv 27 at this point, so as to clear `the large-head and ,at the same time have the pins spaced sufficiently close together so as tov properly en-V gage the cake To this end the wood strip 4 is cutaway at a distance to-th`e frontend Ato the rear of the cakelifter83, asindicated at 102 in Figures l9 and 10,v and the strips 3 at eachfside of the strip4 are cut away for a substantially corresponding' distance at "each side of the cake lifter,v as'indic'ated at Y 103 in Figure 9, sothat .a block 104 of substantially the same lwidthias the lifter head may be interposed between the jends'ofl theblock is of such width as'to leaye o'penings 105y between the lateral edgesof'the block and the adjoining strips 3and has anopenp nal rib 106 on the vunder-side which fits into the channel Airon 9 and yis held in place by screws 107, which are inserted through peris located, and we have therefore provided outwardly extending bracketsor arms 108 on therods 23 atthis point which have iingers-26 extended .upwardlyv therefrom at` their outer ends through the slotsy 105 and then bent inwardly, as indicated in F igure 9, so as to extend over the lateral portionsy of the 'black 104 andapproach sufficiently close to one another so as to insure engagement withY cakes of anyv sizewhich may be dlsired-toluse in connection with this mac ine.

' In order to insure yrelease of the cakes f gfromthe stencil late V56, in case they should cated at 109, are carried'by a vcross-rod 110 tend to adhere t erejto, we mount a releasing in above` and v,concentric with each opening 66 which is adapted to be depressed as the. cake su orting head 83 is moved downwardly. v ese pins, which are indi- Whichextends from` side to side of themachine and hasl the ends engaged and4 secured in boxings 111 at they upper end of shafts or lower the pins 109.

stems 112, eachv of which is mounted in an upright position in the corresponding side frame 1 for vertical o ,eration to raise and y v n the lower endof leach rod 112fis a4 spring 113, one end of which engages against the underside of the frame 1 and thekother end of which bears against a nutv 114 whichis threadedvon the lower end of the rod 112, so as to continually have a tendency to move the rod downwardly and thereby depress the cross-bar 110 and the pins carried thereby. Obviously, this pin-Carr ing frame is .required to be held 1n the elsvated position, except ffor theshort period of time when the cake- Asupports.83 are'lowered, and to effect the proper operation of the pins 109, the hub 115 of each boxing 'lllhas a 'lateral projection to which the upper end of a link 116 is pivoted, and there is al link or arm 117` at e each side of the machine, pivotally mounted thereon, as indicated at 118, and having the forward end pivoted to the lower end vof vthe corresponding link 116. The shaft 97, hereinbefore referred to, which "extends from side to side of the machine and carries the cams 98 for operating the rocker arms 96 which control the operation of the' cakesupports `83, also has a cam 12,0 yadjacent. each endk which engages a roller 121 carried by the rrocker arm`117 intermediate of its ends, the main portion of the periphery of such cam being formed so as -to hold the rocker arms 117 and the` pin-support bar 110 in the elevated position. This cam is cut away at one side, as indicated at 122, so

vas to permitpthe rocker arms 117 and the pin-supportin frame carried thereby tobe y depressed un er the tension of the springs 113, said cutaway portion being arranged with respect to the enlarged portion 100 of `the lcams 98, so that the depression A,of the pin-carrying'frame immediately follows the depression of the cake-supports 83. v The depression of theV lpins 109 occurs as the slide or plunger 53vis being withdrawn, and in order to afford clearance at the lforward edge of the plunger for the pinsas they begin to move downward, there is a ,series of notches v173 in the forward edgefof the slide posed set screws 125, which, are threaded."

'After the cakes .from the magazine 1 0 have been coated with the icing or frosting, it is` oftentimesdesirableto apply another cake on thecoatedlsurface to'provide an article of confectionery in a sandwich form, and to accomplish this result, there are a series of magazines'41 beyond the coating mechanism, which magazines are adjustable in size and constructed and mounted in the samev mannerI as the magazines 10, exce t'that the side-supporting brackets 126 ihr these magazines project above the top ofvthemachine somewhat further than the brackets v11,'` so that the magazines 41 are held with the lower ends thereof `at ahigher elevation than thelower ends of the` magazine 10, for the reasons `which will hereafter appear.

lioo

Each bracket 126 is provided on its inner t at 'a suficient elevation above the upper surface of the strips 3 and 4,'which form kthe top of the machine, so as to provide ample clearance for the coatedl cakes 20 "as Vthey are moved along the upper surface of ,the

machine.

Directly at the rear'of the seriesV` ofk magai zines 4l and at each sideof"the/machinel is a'slide-way composed ofthe rail 1,30 withelevated ends 131 and with a top plate 132 secured to the elevated ends to provide a slot 133 in which a block 134 is mounted to slide,v and there is a plate 135 extending fromside to side of the machine and having the ends thereof secured to the blocks 134. This plate is normally held in the forward position along the rear edge vof the 128, so as to have the cakes 129 movedt ere on from the plate 128, the rear ed e of which latter may be bent downward y, as indicated in Figure 11, if desired, to facilitate the discharge of the vcakes onto the upper surface of the plate 135. This plate 135 is adapted to be withdrawn rearwardly from the normal position during the period of time that lthe cakes 20 are at rest, and the machine is designed so that there will be a seriesof coated cakes 20 `located directly below the position of the cakes 129 on the late 135, so that when the latter is withrawn the cakes..129 fall by gravity down onto the coated surface of the cakes therebelow, as shown in Figure 13. Obviousl the cakes 129 'on the plate 135 must vbe he d against movement with the late 135 when the latter is withdrawn, an y for this purpose, a bar 136 extends from'side to sideof the machine immediately above and adjacent the rear edge of the vplate 135 when the latter is in the normal forward position, and this bar serves as an abutment which holds the cakes on the plate 135 from movement when the. latter is withdrawn and enables said plate to be slid out from underneath the series of cakes thereon. The bar 136 is connected at each end to a bracket 137, which is adjustablysecured in any suitable manner tothe respective strap 132 of the guidesv for the plate 135, said adjustment being desired Ato position the abutment bar 136 at a greater or less distance from the magazines 41 so as to position cakes of different sizes at the proper position above the lower cakes 20.

For feeding the cakes fromk the magazines 41 under the plate 135, the plate 128 is provided with a pair of slots 138 directly under each magazine 41 and spaced apart a less distance than the diameter of the cakes which it is roposed to use-in the magazines, said s ots being extended from the rear edge of the plate 128' to thefront edge of the magazine and leaving, of course, suilicient stock therebeyond, so that the plate 128 maintains its rigidity. The plate may, of course, if desired, be reinforced along the forward edge. A ost, 139 is mounted on each of the side-ro s 21 of the cake-advancing frame, and there is a cross-bar 140 securedl to the upper ends of the posts 139 and extending from side to side of the machine immediate] below the plate 128. Thisfbar is provide with a series of, pins 141 correspending with the slots 138 of the plate 128 and having the forward ends upturned, as

late y indicated inFigure 11, sojas to project up through the slots 108r` suiciently to engage thelowermost cake 129 in the magazine 41 and slide same rearwardly from its position at. the bottom of the stack ofcakesto the required position on the upper surface of the plate' 135. `These pins 141 are preferably arranged for adustment longitudinali of the machine, as s own, for example, in ig ure 11, by threading the stem of the pin and securing same in o enings which extendA through the bar 140 1n the direction of the length of the machine and regulating thead'ustment of the pinb clamp nuts 142.

he plate 135 is with rawn from the normal forward position immediately after the cakes 129 have been moved thereon and while the coated cakesl 20 are at rest on the surface of the machine, and to effect this movement, there isa lever 143 at each side of the machine which has the upper end connected by a link 144 to the corres nding end block 134 of the plate 135, and t e flower ends ofthe levers 142, which extend down to a point near the base of the'machine, are pivoted to the side-frames 1, as indicated at 145. A shaft 146 extends from side to side of the machine and 'hasl the ends journ'aled in the side lframes 1, and there is a crank 147 on each end of the shafty 146 andl at the' outside of the respective frames 1, which cranks are connected by thepitman 148 with the levers 143 intermediate of the ends of the latter.v n

This shaft146 also has A`a cam disc 149 'fixed thereon 'adjacent each end immediately inside the respective frame 1 and provided with va groove 150 in the face thereof of the proper contour to impart the requiredY longitudinal movement to the cakemoving frame 22,23, 27,v and atv the pro er time. Each of the side rods 21; of the ca emovin framehas'acollar 151 thereon with de en ing lugs, between' lwhich the'forward en of a link 152 is pivoted, and each of the links 1,52 has the rear end pivoted` to the upper end of rocker arm 153 which extends downwardly and has the lower end pivoted at 154 to the respective side-frame 1. A rod 155 is pivoted to each rocker arm 153 intermediate of the ends of the latter, and has the forward end forked to provide a long slot 156 which engages the shaft 146. There is a roller 157 on eachV rod 155y which is engaged in the groove 150 ot'v the respective cam disc 149, so thatv upon rotation of the shaft 146, the rocker arms 153 are caused to operate in unison and effect the required recprocating movement of the cake-advancing frame.r V, 4

At the rear end of the machinethe strips 3 andl 4 are preferably extended some distance beyond the magazines 41, and the extension bars 28 are provided on the main cake-advancing frame 22,23, 27 to continue
